The 180C clamp-style filter is a more compact and lightweight alternative to the standard 180 Series self-cleaning filter. The filter accommodates simple online installation, with the water-saving advantage of using a single 1-in. flush valve. Flush volume is as little as 4 to 12 gal per backwash. The filters are ideal for irrigation, municipal or industrial applications where installation footprint, weight or flush volume are of concern.
